Referring to fig. 1 to 6, a rotating shaft structure according to a preferred embodiment of the present invention includes a first rotating base 100, a second rotating base 200 pivotally connected to the first rotating base 100, and a limiting roller 300 interposed between the first rotating base 100 and the second rotating base 200. The first rotating base 100 is pivoted to the second rotating base 200 to enable the first rotating base 100 and the second rotating base 200 to pivot relatively, and the limiting roller 300 can limit the stroke of the relative pivoting, which will be described in detail later.
In the present embodiment, the first rotating base 100 is preferably a hollow base made of metal. The first rotating base 100 can be connected to an end of a radial arm 10 according to the use requirement, and the first rotating base 100 is preferably sleeved with the radial arm 10 and locked by a screw in the transverse direction of the radial arm 10. The first rotary base 100 is formed with a shaft tube 110, and the shaft tube 110 extends in a direction perpendicular to the swing arm 10. A first arc groove 101 is concavely disposed on an outer wall surface of the first rotating base 100, an opening direction of the first arc groove 101 is the same as an extending direction of the shaft tube 110, and the first arc groove 101 surrounds a portion of the outer side of the shaft tube 110. The extension arc of the first arc groove 101 is set according to a predetermined total arc of the relative pivotal stroke of the first rotary base 100 and the second rotary base 200.
In this embodiment, the second rotating base 200 is preferably a hollow base made of metal. The second rotating base 200 is connected to one end of another radial arm 10 according to the use requirement, and the second rotating base 200 is preferably sleeved with the radial arm 10 and locked by screws in the transverse direction of the radial arm 10. The wire 20 can pass through the two swing arms 10, the first rotary base 100 and the second rotary base 200. The second rotating base 200 is formed with an outer sleeve 210, the extending direction of the outer sleeve 210 is perpendicular to the rotating arm 10, and the outer sleeve 210 is pivotally sleeved on the shaft tube 110 to make the second rotating base 200 pivotally connected to the first rotating base 100. A second arc groove 201 is concavely provided on the outer wall surface of the second rotary base 200, the opening direction of the second arc groove 201 is the same as the extending direction of the outer sleeve 210, and the second arc groove 201 surrounds a part of the outer side of the outer sleeve 210. The second arc groove 201 is disposed opposite to the first arc groove 101, and the arc centers of the first arc groove 101 and the second arc groove 201 are located on the relative pivot axes of the first rotating base 100 and the second rotating base 200. The extension arc of the second arc groove 201 is set according to the total arc of the predetermined relative pivotal stroke of the first rotary base 100 and the second rotary base 200. The sum of the extension radian of the first arc groove 101 and the extension radian of the second arc groove 201 is the total radian of the relative pivoting stroke predetermined by the first rotating base 100 and the second rotating base 200.
In this embodiment, the outer wall surface of the shaft tube 110 is formed with an outer thread 111 and a longitudinal groove 112 extending parallel to the central axis of the shaft tube 110, and the longitudinal groove 112 preferably extends across the outer thread 111. An inner flange 211 is protruded from an inner wall surface of the outer sleeve 210, a nut 220 is threadedly engaged with the outer thread 111 of the shaft tube 110, and the nut 220 stops the inner flange 211 to prevent the shaft tube 110 from slipping off the outer sleeve 210, thereby fixing the shaft tube 110 and the outer sleeve 210 to each other.
The shaft tube 110 is sleeved with a fixing ring 240, and the fixing ring 240 is clamped between the outer wall surface of the shaft tube 110 and the inner wall surface of the outer sleeve 210, thereby being supported between the shaft tube 110 and the outer sleeve 210 so that the shaft tube 110 and the outer sleeve 210 can stably pivot relatively. The outer side wall of the fixing ring 240 is protruded with an outer flange 241, and the outer flange 241 is between the nut 220 and the inner flange 211 of the sleeve, so it can also be used to stop the inner flange 211 of the outer sleeve 210.
The shaft tube 110 is sleeved with a slip stop ring 230, and the slip stop ring 230 is preferably located on the side of the nut 220 opposite to the shaft tube 110 and contacts the nut 220. A tenon 231 is convexly arranged on the inner edge of the slip stopping ring 230, the tenon 231 is clamped with the longitudinal groove 112, so that the slip stopping ring 230 cannot rotate, and the nut 220 is tightly pressed on the slip stopping ring 230. Since the slip-stopping ring 230 cannot rotate, when the shaft tube 110 and the outer sleeve 210 pivot relatively, the nut 220 is not pulled by the shaft tube 110 and the outer sleeve 210 to rotate and be loosened.
The second rotating base 200 has a through opening 202 corresponding to the nut 220, and the through opening 202 is closed by a door 203. The nut 220 has at least one notch 221 formed in its outer edge, and a user may remove the door 203 and lock the nut 220 by snapping a tool into the notch 221 of the nut 220 through the opening 202.
The limiting roller 300 is clamped between the first rotating base 100 and the second rotating base 200, one half of the limiting roller 300 is accommodated in the first arc groove 101, and the other half of the limiting roller 300 is accommodated in the second arc groove 201. The first arc groove 101 or the second arc groove 201 is sleeved with a gasket 120, and the gasket 120 is preferably made of plastic and is softer than the inner wall surface of the first arc groove 101 or the second arc groove 201. The shape of the liner 120 is matched with the first arc groove 101 or the second arc groove 201, the liner 120 is convexly provided with a positioning tenon 121, the positioning tenon 121 is embedded into the first rotating base 100 to fix the liner 120, and the limiting roller 300 abuts against the liner 120 to avoid abrasion of the first arc groove 101 or the second arc groove 201. Specifically, the pad 120 is formed with a groove portion 122 corresponding to the shape of the inner wall of the first arc groove 101, the groove portion 122 is recessed on one surface of the pad 120 and protruded on the other surface of the pad 120, the protruded surface of the groove portion 122 is adhered to the inner wall of the first arc groove 101, and the stopper roller 300 is abutted against the recessed surface of the groove portion 122.
Referring to fig. 6 to 7, the rotation axis structure of the present invention defines the two-way end point of the relative rotation of the first rotation base 100 and the second rotation base 200 by the first arc groove 101, the second arc groove 201 and the limiting roller 300. Specifically, when the first arc groove 101 and the second arc groove 201 relatively rotate along a direction, the first arc groove 101 and the second arc groove 201 are gradually separated from each other, so that a space for accommodating the limiting roller 300 is gradually reduced when the first arc groove 101 and the second arc groove 201 are overlapped. When the first arc groove 101 and the second arc groove 201 continue to rotate relatively until the overlapping space is reduced to a point where only one end of the first arc groove 101 is overlapped with one end of the second arc groove 201, the limiting roller 300 is blocked between the two ends so that the two ends cannot be separated from each other. Thereby, the relative rotation between the first arc groove 101 and the second arc groove 201 cannot be continued, and the end point of the pivoting stroke in this direction is defined. When the first arc groove 101 and the second arc groove 201 rotate relatively in the other opposite direction, the end point of the reverse pivoting stroke is defined by the limiting roller 300 in the same manner. In the present embodiment, the first arc groove 101 and the second arc groove 201 extend 180 degrees, respectively, so that the relative pivotal travel of the first rotating base 100 and the second rotating base 200 is the sum of the extension arc of the first arc groove 101 and the extension arc of the second arc groove 201, i.e. 360 degrees.
In summary, the first arc groove 101, the second arc groove 201 and the limiting roller 300 of the rotating shaft structure of the present invention have better structural strength than the conventional stopper, so that the stopper is less prone to damage, and the rolling of the limiting roller 300 does not affect the relative rotation of the first rotating base 100 and the second rotating base 200.
The above description is only a preferred embodiment of the present invention, and is not intended to limit the scope of the present invention, and other equivalents made by the spirit of the present invention should fall within the scope of the present invention.
